FilmTec™ SW30XFR-400/34(i)

Summary

Product identification

The FilmTec™ SW30XFR-400/34i Element is a spiral-wound element featuring a polyamide thin-film composite membrane, specifically designed to handle biofouling in seawater desalination plants. It is equipped with advanced fouling-resistant and cleanability features, aiming to reduce the number of chemical cleanings and improve system uptime.

Key benefits include:

• Fouling-resistant design, reducing chemical cleanings by more than 33% relative to a leading fouling-resistant product.
• Durable membrane chemistry for stable, high rejection despite repeated chemical cleanings.
• Low element differential pressure, improving system hydraulic balance.
• More effective and efficient cleaning of biofilm, organic compounds, and scale, achieved through a wide pH range in cleaning (pH 1 – 13).
• Utilization of iLEC™ Interlocking Endcaps to help reduce system operating costs and O-ring leak risks.

Typical Properties

Normalized Conditions:

1. 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa), 77°F (25°C), pH 8, 8% recovery.
2. Permeate flows for individual elements may vary ± 15%.
3. Minimum Salt Rejection is 99.65%.
4. Stabilized salt rejection is generally achieved within 24–48 hours of continuous use.
5. Active area guaranteed ± 5%.

Customer Notice

• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction depends on complete system design and on the operation and maintenance of the system.
• Permeate obtained from the first hour of operation should be discarded.

Regulatory Note

This product may be subject to drinking water application restrictions in some countries; please check the application status before use and sale.
